BTW: nothing changes if the VM is powered off when I take the
snapshot. A following clone operation remains with the white window I
sent before...
NOTE: On February 5th on this same infra I was with engine and node at
nightly repo as of vdsm-4.10.3-0.78.gitb005b54.fc18.x86_64 and I was
able to successfully complete this kind of operation. It was done with
the VM powered off.
